It features a 0.04 inch cutting diameter and a 0.12 inch length of cut, with four flutes ground from micrograin carbide for edge retention and surface finish quality. The AlTiN coating adds thermal resistance and hardness, making this tool suitable for cutting hardened steels, stainless, and other difficult alloys at elevated speeds. At 1.5 inches overall length with a 0.125 inch shank diameter, this is a small-diameter tool used by machinists and tool and die tradespeople for detailed slot milling, profiling, and finishing work.\u003c\/p\u003e\u003cp\u003eThis end mill fits applications requiring tight tolerances in small-feature geometry. The 30-degree helix promotes smooth chip evacuation in short-cutting-length passes. It is a single-end, right-hand cut, right-hand flute tool classified as regular length. Typical uses include precision slot cutting, pocket milling, and contour work on hardened ferrous and non-ferrous materials in job shop, aerospace, and mold and die environments. The mill diameter tolerance is +0.0000 \/ -0.0010 inches and the shank diameter tolerance is -0.0001 \/ -0.0003 inches.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e0.04 inch cutting diameter with micrograin solid carbide construction for wear resistance\u003c\/li\u003e\n\u003cli\u003eAlTiN coating provides elevated thermal hardness for dry or high-speed cutting\u003c\/li\u003e\n\u003cli\u003e4-flute, 30-degree right-hand spiral helix for efficient chip evacuation\u003c\/li\u003e\n\u003cli\u003eCentercutting design allows direct plunge entry into workpiece\u003c\/li\u003e\n\u003cli\u003eTight mill diameter tolerance of +0.0000 \/ -0.0010 inches for precision fitment\u003c\/li\u003e\n\u003cli\u003eSingle-end configuration, regular length at 1.5 inches OAL\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or direct-use solid carbide square end mill suitable for CNC machining centers and manual mills accepting a 0.125 inch round shank.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eThis tool is installed and changed by qualified machinists or CNC operators. Ensure the spindle is fully stopped and locked out before changing tooling. Use a calibrated collet or end mill holder sized for a 0.125 inch shank and torque to the machine manufacturer's specification. Inspect the cutting edges and coating before each use; do not run a chipped or worn tool, as small-diameter carbide end mills are brittle under lateral shock loading.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.04 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 0.12 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 1.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.125 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 4\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 30 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Spiral\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: AlTiN\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEnd Mill Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: Micrograin\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCentercutting\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eExtended Reach\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eVariable Helix\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eChipbreaker\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength Type\u003c\/strong\u003e: Regular\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter Tolerance\u003c\/strong\u003e: +0.0000 \/ -0.0010 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter Tolerance\u003c\/strong\u003e: -0.0001 \/ -0.0003 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.1 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: ACCUPRO\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 12462871\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51731014123826,"sku":"12462871","price":31.32,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/4f94b0ea18260bae0a644d13ec2172e1.jpg?v=1788725874","url":"https:\/\/voomisupply.com\/products\/accupro-12462871-square-end-mill-0-04in-4-flute-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
